베네치안 블라인드의 슬래트 각도 조정은 사람에 따라 주관적이다. 그러므로, 제어 규칙에 인가된 초기의 데이타로는 에너지 절감 효과에 효율적이지 못하다. 본 논문에서는 퍼지 베네치안 블라인드 제어기를 설계 및 구현하였다. 여기에서는 외부 환경에 잘 적응할 수 있는 퍼지 제어 규칙 및 소속함수를 tuning 할 수 있는 방법을 제안하였다. 그리고 입력 에너지, 실내 환경 및 조명을 충분히 고려하여 에너지 절감 정도를 분석 및 평가하였다. 하절기와 동절기로 나누어 각각 실험한 결과 퍼지 이론을 적용하여 자동으로 슬태트 각도가 제어되는 시스템의 에너지 절감 효과를 얻을 수 있었다.

Generally, among many kinds of shading devices such as venetian blind, sunscreen, louver and curtain, venetian blind is using widely because the mechanism is so simple and easy to use solar insolation by controlling the slat angle. Analysis of time dependent heat transfer through the window with venetian blind is very important in order to use it effectivly. Therefore, in this study, theoretical thermal analysis method was developed to analyze time dependent heat transfer through a double pane window with and without venetian blind, and was made one module of TRNSYS(A Transient Simulation Program)program. By this way, it was analyzed that how much the variation of slat angle, slat colour and slat absorptivity of venetian blind would be affected on the heating and cooling load of building, and also which colour and angle of slat was optimal for the heating and cooling load of building.

Current Architectural Facade Designs have been trending to increased glass areas resulting in increasing impact on interior lighting and daylighting. In regards to indoor environmental quality, the increase in window space has a large impact on the daylighting received which ultimately impacts the liveability of a space. Especially when considering seasons, in the summer, excessive daylighting can result in glare as well as put an increased load in conditioning the air space further reducing energy efficiency. As a result, in order to improve the sustainability performance of a building, it is important to limit the natural lighting exposure to properly meet the needs and conditions of the building occupants. One of the most representative features to limit excessive sunlight exposure, is to incorporate operable blind systems. To this end, this research has been based on simulations performance through the Radiance Program. Radiance is capable of analyzing performance of daylight and impact of sunlight. Through analysis of different slat angles and blind shapes, impact and minimization of energy usage was evaluated. Furthermore, seasonal analysis was performed in order to understand the effects of seasonal climate factors. Ultimately this research provides an analysis of operable blinds optimization and effects of blind shape, control factors and angle of shading.

재귀 반사체(Retro Reflector)는 그 반사특성을 살려 베네치안 블라인드 슬랏, 디스플레이, 그리고 교통 안전 분야 등에서 활용 영역이 넓어져 가고 있다. 재귀 반사율 분포를 조절할 수 있는 코너 큐브 재귀 반사체를 정의하고, 입사각도에 따라 그 재귀반사광의 특성을 분석하여 교통 안전 분야에 적용하고자 하였다. 특성 분석 결과를 용이하게 파악할 수 있도록 시각화한 특성 도표를 고안하였으며, 이를 이용하여 다양한 교통 안전 분야의 재귀 반사 시트를 정량적으로 설계할 수 있음을 보였다.

Venetian blinds are used with windows to improve the uniformity ratio of illuminance and interior daylighting distribution under direct sunlit conditions. The main objective of Venetian blinds shading system is to obstruct direct sunlight and at the same time allow daylight to penetrate into the room. Venetian blinds would have greater effect on the interior daylighting condition under clear sky which has both skylight and sunlight than overcast sky which has only skylight. However, due to the lack of data, design and evaluation tools, it is difficult for architects to choose or install venetian blinds during the building design stages. The purpose of this study was to develop an analysis method for shading and daylighting effects of Venetian blinds using the RADIANCE program. The major variables related to the venetian blinds included blinds's slat angle and the ratio of slat width to window height, the radius slat of curvature and the building azimuth. In this study, a series of parametric physical mock-up model measurements and genblinds command in the RADIANCE simulations. The results of this study will provide building designers with the design data at early design stages.
